How to calculate oxygen fugacity
WebOxygen fugacity (fO 2) is a fundamental variable affecting phase equilibrium in magmas, and in externally heated pressure vessel experiments it is typically controlled by using redox buffer assemblages.However, these do not allow fine enough resolution; for example, most arc magmas fall between the fO 2 imposed by the neighboring Ni–NiO and Re– …
